We now use SUBSCRIBE instead of PEEK to maintain the desired set of updates that need to be written. We also don't acquire locks on tables but instead optimistically try and write our updates at the timestamp right at our current subscribe frontier. Additionally, we take the opportunity this provides and move the sequencing code from the coordinator main loop to the frontend, similar to how we have done that for peeks in frontend_peek.rs.
